[Acromegaly and pregnancy].

Acromegaly usually results from GH hypersecretion by a somatotroph adenoma. The fertility of acromegalic patients is often impaired. Several factors may impact the course of pregnancy in acromegaly. Disturbed pituitary function might lead to infertility or spontaneous abortion. GH is a powerful insulin antagonist, and pregnant acromegalic patients are prone to added glucose intolerance and diabetes. Pregnancy itself might also impact the course of the pituitary tumor. During pregnancy, the normal pituitary increases in size due to estrogens-mediated hyperplasia. Therefore, tumors are at risk for hemorrhage due to enhanced vascularity, and might compress the optic chiasm. In this article we summarize the data on the literature on the reciprocal influences between acromegaly and pregnancy, we discuss therapeutic options and advance diagnostic and surveillance schedules of acromegaly during pregnancy.
